The Study Of Waterflow Automatically Adjustmenting Device

Water flooding is the main method to enhance oil recovery. Nowadays several oilfields apply theeccentric water distribution pipe string technique to improve oil production. The now available eccentricwater distribution methods: at first, according to the real and the theoretical water distribution volume ofthe layers, choose a water nozzle of same size, put it in the packer; then test the real injection volume ofthe layers. If the real injection volume can't reach the volume that the develop plan needs, bring out thepacker and change the water nozzle, then put it in and test the real injection volume again. These jobsshould be done over and over until the real injection volume reaches the volume that the develop planneeds. Along with the more and more rigorous injector layered reservoir test, this technology is lowefficient and needs lots of workload. So in order to solve this difficult problem, equipment which canadjust the water injection volume has been invented successfully.Through the research of the automatically controlled water volume equipment, the integrativedevices that has abilities of adjusting water nozzle, adjusting control, non-affiux test has come into being.Then make further research of the part of casting and scooping up control, ensui'e the adjusting entity canconnect and depart with the host under the well; receive the flux rate signal; control the machine rotation.At last through the research of adjusting the bore diameter ofthe water nozzle and setting the expectingflux rate value, and research of the playback of the control device test and adjustment data curves, makeit can be completed by playback equipment, PDA or micro computer. And through the research of thewater volume adjustment equipments' range of application and applicable layers, moreover thelaboratory examination and field test, improve the instrument and make it efficiently suit for the eccentricwater distribution of water wells.
